GATE.

SPECIFICATION forming part of Letters liatentl No. 589,134, dated August31, 1897?` Application filed May 24, 1897. Serial No. 637,842.. (Nomodel.)

To @ZZ whom it may concern: Y

Be it known that I, JACOB B. MIESSE, a citizen o f the United States,residing at Nobles-A Y Ville, in the county of Hamilton and State ofIndiana, have in vented'a new and useful Gate, of which the following isa specification.

My invention relates to an improvement in automatic sliding gates.

The object'of my invention is to provide mechanism by means of which asliding gate, may be automatically opened or closed by the passage ofavehicle along the roadway leading through such gate.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation showing the gate closed. Fig. 2 is a sideVelevation showing/the gate open. Fig. 3 is a plan of Fig. l. Fig. 4 isa sectional detailof the pivoted guide and the sliding weight mountedtherein.

In the drawings, 6 indicates the gate-posts, to the'upper ends of whichis secured a transverse track 7. Posts 6 consist, preferably, of twosections, between which the gate may move, but single posts maybe'used,if desired. Mounted beneath track 7 and suspended therefrom bymeans of rollers 8 are two gatesections 9 andlO, the arrangement beingsuch that the said gate-sections may be mpved along said track ac rossthe roadway. Mounted to one side of the road, near one of the posts 6,is a post 11.` Pivoted upon post 11, so as Ito swing in a planesubstantially parallel with the plane of the gate, is a guide l2, withinwhich is mounted a sliding weight 13, provided with suitable .rollers13". Extending upward from weight 12 is a shank 14, through which anopening 15 is formed substantially at right angles to the path ofmovement of l oted to the gate-section 9.

the weight. Mounted in opening l5 and secured therein by means of aset-screw 16 is an arm 17, the outer end of which lies within a slot 18,formed in the outer or free end of an arm 19, 'the opposite end of whichis piv- Pivoted near post 11, so as to swing in a substantiallyhorizontal plane, is a lever 20, to each end of which is secured a cord2l. Each of cords 2l is passed beneath a pulley'22, which is carried bya yoke 22", pivoted so as to swing in a substantially horizontal plane,and the ends of said cords are secured to guide 12, one to each side ofthe pivot thereof.

Mounted at each side of the gate, at some distance along the roadwaytherefrom, is an operating-lever 23 of the usual well-known form,`thesaid lever being provided with a pair of arms 24 and 25, which areadapted to be engaged by the wheels of vehicles. Secured to lever 23 isa link 26, the opposite end of which is pivoted to one arm of lever 20,the throw of said lever being regulated by placing the end of said linkwithin any one of a series of holes 27, placed at different distanceslfrom the center of the lever. In order to cause the two gate-sectionsto move simultaneously in opposite directions, I secure to the upper endof section 9 a rack-bar 23, and to section 10 is secured a similarrack-bar 29, the said rackbars lying parallel with each other andtheteeth thereof engaging opposite sides of a small pinion 30. By thismeans any movement of section 9 causes, through the rackbars and pinion,a corresponding opposite movement of section lO. The rack-bars23 and29are hield in engagement with pinion 30 by means of small idlers 3l. Inorder to protect the interior of guide 12 from rain, snow, dsc., I mountover the upper part thereof a hood 32, beneath which shank 14 of thesliding'weight moves, a slot 33 being formed .through one side of said'hood to permit the passageof arm 17. The hood 32 is shown in detail inFig. 4, but has been omitted from the other figures for the sakelofclearness. It is advisable to protectutra'ck7 and the parts operatingthereon, and for this p urpose I-fprovide a 'oof 34. (Indicated indotted lines in Fig. 1.

The operation is as follows: Supposing the gate to be closed,the-various parts will be in the position shown in Fig. y1. The wheelsof one side of a vehicle passing along the roadway toward the gate willcomein contact with arm 24 of one of levers 23 and force the said leverforward and downward. This movement of lever 23 causes-a swingingmovement of lever 20, which, through cords 21, causes guide 12 to swingupon its pivot, thus raising weight 13 above the pivot of .the guide.Weight 13 then slides downward along guide 12, carrying with it arm 19and gate-section IOO 9, to whieh itis pivoted. The outward movement ofsection 9 Causes, through rack-bar 2S, pinion 30, and1aek-bar29,aCorresponding outward movement of gate-section 10. The vehicle thenpasses through and comes into engagement with arm 25 of the other leverThis causes guide 12 to return to its original position, when weight 13again slides downward along the guide and returns the various parts tothe original position.

It will be noticed that in either position of the gate weight 13 holdsarm 17 in engagement with one end or the other of slot 1S of arm 1), sothat the said weight operates to prevent the accidental opening orclosing of the gate.

I claim as my invention- 1. The combination with a gate, of a pivotedguide, a weight mounted so as to slide along said guide, an arm pivotedto the gate, an arm carried by the weight and adapted to engage saidrst-mentioned arm, and means for swinging the guide.

2. The combination with a gate, of a pivoted guide, a weight mounted soas to slide along said guide, intermediate connecting mechanism betweensaid weight and gate whereby a down ward movement of the weight alongthe guide will cause a movement of the gate, an operating-lever 23mounted in the roadway, and intermediate oonneeting meehanism betweensaid lever and the pivoted guide whereby the operation of said leverwill eause a swinging movement of the guide.

3. The combination with a gate, of a pivoted guide, a weight mounted soas to move along said guide, an arm Carried by said weight, an armpivoted to the gate and adapted to engage said iirst-mentioned arm, anoperatinglever 23 mounted in the roadway,

lever 20, eords 21 connecting the ends of said lever with opposite endsof the pivoted guide, and a link connecting levers 23 and 20, allcombined and arranged to cooperate substantially as and for the .purposeset forth.

l. The combination with a pair of sliding gate-sections, of a pivotedguide, a weight mounted so as to slide thereon, intermediate connectingmechanism between said weight and one of the gate-sections, means forswinging the pivoted guide, and intermediate eonneeting mechanismbetween the two gate-seetions whereby a movement of one of said sectionswill eause a similar opposite movement of the other seetion.

rlhe Combination with a pair of sliding gate-sections, of a pivotedguide, a weight mounted so as to move along said guide, intermediateconnecting mechanism between said weight and one of the gate-sections,means for swinging the pivoted guide, a raekbar Carried by each oi thegate-sections, and a pinion engaging both oi' said rack-bars, allcombined and arranged to cooperate substantially as and for the purposeset forth.

6. The Combination with a pair of sliding gate-sections, of a pivotedguide, a weight mounted so as to slide thereon and provided withsuitable rollers7 an arm earried by one of the gate-sections and adaptedto engage the weight, a rack-bar carried by eaeh gatesection, a pinionengaging both rack-bars, lever Q3 mounted in the roadway, lever 20,eords 2l, and link 2G, all combined and arranged to cooperatesubstantially as and for the purpose set forth.
